Question

If the mid point of line segment AB is (1,1) &B(4,3) then find the co ordinate of A

Answer 1

Answer:

A(-2,-1)

Step-by-step explanation:

as per the question given

x1+x2/2 , y1+y2/2 = (1,1)

x+4/2 , y+3/2 = (1,1)

x+4/2=1 , y+3/2=1

x+4=2 , y+3=2 (cross multiplication)

x=2-4 , y=2-3

x=-2 , y= -1

therefore the answer is (-2,-1)
